Abstract
A direct path (D-PATH) to be used by a call link is set up in advance between all of the nodes. A connection link is to use a route separate from this direct path. In this way, if layer incompatibility is detected between a transmission terminal (13) and a receiving terminal (13) at the time of a call link, a connection path (C-PATH) separate from the direct path (D-PATH) is set up from a transmission node (8) to a receiving node (8) via a data exchange node. In this way various B-ISDN services can be realized.
